The Conquest of Britannia charts the 40 years from when Roman Legions landed on Britannia's shores in AD43 to Romanising nearly all of Britannia, including major events which happened in this period.
All historical events will be shown in the requests/orders from Rome.

Starting in the small south eastern coastal settlement at Dubris, Rome instructs you to assist in it's conquest of the tin island. If successful, your reward will be promotion to the top ranks of the empire.

Did have some frustration because instructions were not clear to me. Meaning, building 2 coliseums would get me fired / lose the scenario. However, the instructions are vague. They state something about "coliseums should not exceed rome in granduer".
